Serious misconduct by WA public servant

A former Horizon Power technology manager who secretly got the WA state-owned utility to pay his company ongoing fees may face criminal charges after the corruption watchdog found he engaged in serious misconduct.

The Corruption and Crime Commission investigated Paul Thomas and discovered he had used his position to falsely claim a company he owned, Trusted Solutions IT, was carrying out work for Horizon.

Mr Thomas also engaged his business partner Anthony Raspa to work at Horizon.

For several years, they plotted to exploit the utility for their own gain, funnelling hundreds of thousands of dollars into their business.

The CCC has recommended prosecutors consider charging the three men with conspiracy to commit fraud.

The report comes days after the CCC revealed three former senior public servants had pocketed tens of thousands of dollars worth of cash and gift bribes from contractors over a decade when they worked for the North Metropolitan Health Service.

Opposition spokesman for government accountability Tjorn Sibma called for a wide-ranging independent review into public sector procurement practices.

"I think the public are absolutely angry about the revelations from last week and today," Mr Sibma told reporters.
